Part of 🌰︎ chestnut / chinkapin genus Castanea in beech / oak family Fagaceae in bayberry / beech / birch / oak / walnut order Fagales.

Native to eastern 🇺🇸 USA and very-southern 🇨🇦 Canada. 🗺 Map by county (🇺🇸 USA-48) (color key), 🗺 map (North America, Central America), 🗺 map (eastern 🇺🇸 USA).

Formerly abundant and a major component of the Eastern hardwood forest, this tree is almost extinct in the wild, having been killed by a bark fungal disease chestnut blight Cryphonectria parasitica.

Although I see that my local Conservation District is selling bare-root trees of this species, but grown from in-state survivors of the blight, known to be resistant. Worth a try, to resurrect this amazing piece of Americana!

The disease also impacts (not quite as hard) this tree's closely-related (even shares most of its home range) sister-species Allegheny chinquapin Castanea pumila.

Uses by native peoples
